oil and gas,petrochemicals and power plant engineers and technicians interview question and answers for electrical and instrumentation. 1.     fire tu*e boiler – fire inside the tu*e and water outside the tu*e.. 2.     water tu*e boiler – water flow inside the tu*e and fire outside the tu*e.. distillation unit side view showing brine recirculation pump. turbine is a prime mover. it can rotate pump, compressor, alternator etc.             there are three types             1. gas turbine.             gas fired directly inside the casing and diffuser, heat power rotates the rotary..             water pressurized then injected through nazzle and vanes, it can be rotated rotary..             the entire turbine should be governed by governor.                         (governor-speed controlling mechanism for variation of load.). types of steam turbine:- 1.     evaporation type- more than atmosphere pressure.. 2.     condensate type-less than atmosphere pressure.. types of water turbine:- 1.     impulse type-water directly the injected in vanes.. 2.     reaction type-water indirectly the injected in venes.                                                             (api stands-american petroleum institute.)                                       process variables:              steam temperature          :           535⁰c  steam pressure                  :           150 bar  rpm                                       :           3000  capacity                                :           300 mw  make                                      :           toshiba, japan.
